About this model

Plumbed into the water supply and the drain, the station of the Roborock S8 Max Ultra with Refill & Drainage System fills and empties itself, something fewer than a quarter of stations that wash the mop can do. It stands 11.8 inches high, 7.9 inches under the norm, low enough for the space beneath a worktop. The sonic mop lifts 0.8 inches, and 0.4 inches is the ordinary lift, so the pad rides above a thicker rug.
